About
Chunhai Jiao is a leading researcher in the field of wearable robotics, with a primary focus on the design and actuation of lower-limb exoskeletons and prostheses. His work centers on solving a fundamental challenge in the field: creating actuators that are simultaneously lightweight, highly backdrivable (compliant), and possess high bandwidth for agile, natural movement. Jiao’s major contribution is the development and modeling of quasi-direct drive (QDD) actuation systems. His most cited work, a 2020 paper on a lightweight hip exoskeleton (165 citations), demonstrates how QDD can overcome the limitations of traditional series elastic actuators (SEAs), which often sacrifice bandwidth for compliance. He further extended this concept to a portable, high-torque robotic knee prosthesis (2022), designed to support demanding activities like running and squatting. By achieving high intrinsic compliance without compromising power, Jiao’s designs enable wearable robots that are both safe and high-performance. His research is pivotal for advancing the mechanical versatility of assistive devices, directly impacting the development of next-generation, agile rehabilitation and augmentation technologies.
